诗歌是暗示的艺术，而非断言的艺术。

If you're not stubborn, you'll give up on experiments too soon. And if you're not flexible, you'll pound your head against the wall and you won't see a different solution to a problem you're trying to solve.

The most successful organizations are those that focus on creating value for all stakeholders.

可持续性不是一种选择；它是我们对下一代的责任。
